TLV5638M: Proper VDD Question

Joseph Tudino

Prodigy 20 points

Part Number: TLV5638M
Other Parts Discussed in Thread: TMS320F28335,

In the datasheet for the TLV5638M, specifications are mostly focused on the cases where VDD = 3V or VDD = 5V. Is it proper and an intended use case to use this part with VDD = 3.3V? I want to use this part in conjunction with the TMS320F28335, which operates at 3.3V.

Thank you,

Hi Joseph,

What are you using as a reference? 3.3V is an acceptable supply voltage, I am not sure why the original datasheet writers used 3V instead.

Thanks,

Paul

I haven't decided what reference I'll be using, but I'm leaning towards using the internal 1.024V reference

Hi Tudino,

You can use 1.024V as reference for 3.3V supply without any issues.

Let me know if you need any other assistance.

Regards,
